15 TOOLBAR Please refer to section Toolbar Help on this manual. FACEPLATE AND DETAIL PICTURES GENERAL To open a Faceplate or Detail picture for a module using the standard button in the upper left corner of the Main window, the module must first be selected by clicking on one of its data links. The Faceplate allows access to the most important operating parameters. The Detail picture provides access to almost all tuning parameters and diagnostic information. DeltaV Library module templates have prebuilt Faceplate, Detail and Trend pictures as well as customized ones. If the module doesn't have a selectable link, you can choose the module by clicking on the large Faceplate (or Detail) picture button in the main Toolbar. A dialog box opens in which you can enter the module name. The appropriate Faceplate or Detail picture pops up and the module name is added to the Module History list, which is similar to the Display History list. This list lets you select, for any module listed, the Faceplate, Detail, or Primary Control picture. As with the Display History list, the Module History list can be pre-populated and locked using the UserSettings file. Below you can find a detailed description of more complicated PID- and Device Control Block faceplates and details. For more information on this subject please refer to DeltaV Books Online. FACEPLATE Power Boiler Training Simulator 15 of 33

16 The following items are contained in the PID function block faceplate: Position button This button is used to toggle the position of the faceplate to the left or right side of the screen. Each time the display is opened, it defaults to the most recent position. Close Faceplate button This button is used to close the faceplate. Bypass This area is visible if the Bypass Enable option is set in CONTROL_OPTS (typically when the PID block is a slave in a cascade pair). Click Bypass to place the PID block in Bypass mode. This makes the output value equal to the % SP value, which allows the master loop to drive the output if the transmitter is unavailable. Click Normal to turn off the Bypass mode. Tag name - Tag names of modules that use this faceplate must be limited to 12 or fewer characters. If the tag name has more than 12 characters, the faceplate will not be opened. OUT_READBACK This area displays the OUT_READBACK value of the PID block in cyan. The background color of the 3-D box changes from black to orange or red when the Output status becomes uncertain or bad, respectively. In the absence of a configured IO_READBACK DST, the OUT_READBACK value shown is equal to the implied output value of the loop. The displayed decimal format of OUT_READBACK is determined by the OUT_SCALE.F_DECPT parameter field. The value of this field corresponds to the number of digits displayed past the decimal point. The values of OUT_SCALE.F_DECPT that are supported by this faceplate are 0, 1, 2, and 3. No value is displayed when the value in the OUT_SCALE.F_DECPT field is larger than three. Clicking this box while the target mode of the block is MAN or OOS produces a dialog prompting the operator for an Output value. The valid range for input is defined by the EU0 and EU100 values of the OUT_SCALE parameter. Valid input ranges from -10 percent to 110 percent of OUT_SCALE. PV This area displays the PV value of the PID block in yellow. The background color of the 3- D box changes from black to orange or red when the PV status becomes uncertain or bad, respectively. The PV value is visible in the decimal format provided by PV_SCALE.F_DECPT when this value has 0, 1, 2, or 3 digits. Output Units This is the engineering units description for the Output as defined in the OUT_SCALE parameter. PV Units This is the engineering units description for the PV as defined in the PV_SCALE parameter. Output EU 100 This is the value corresponding to 100% of scale for the Output. PV EU 100 This is the value corresponding to 100% of scale for the PV. CAS/AUTO/MAN buttons These buttons are used to set the target mode of the PID block to the corresponding mode. The visibility of these three buttons is based on permitted modes of the PID block. Buttons for CAS, AUTO, and MAN mode are displayed when the respective mode is a permitted mode. Mode button This button is used to display a list of the target modes available for the block. Click one of the permitted modes to set the block target mode to that mode. To close the mode selector box, click the X button. Target Mode This field contains a word in white text that describes the target mode for the block. Actual Mode This field contains a word in yellow text that describes the actual mode of the block. Setpoint slew keys These gray buttons with a white arrowhead pointing up or down are used to increment or decrement the setpoint value by 1 PV engineering unit if PV_SCALE.F_DECPT is less than or equal to 1. If PV_SCALE.F_DECPT is 2 or greater, each click changes the setpoint by 0.1 engineering unit. The setpoint slew keys are visible if the target mode is AUTO, MAN, or OOS. Output slew keys These gray buttons with a cyan arrowhead pointing up or down are displayed below the Setpoint Slew keys only when the loop has a target mode of MAN or OOS. Click the up arrow or down arrow to increment or decrement the Output value by 1 Output engineering unit. Output bar graph This field indicates the value of OUT_READBACK, which is the same as the value displayed in the OUT_READBACK display box. Power Boiler Training Simulator 16 of 33

17 Output Slider This large cyan arrowhead to the left of the Output bar graph is displayed only when the target mode of the block is MAN or OOS. To move this button, hold down the left mouse button while the cursor is over the arrowhead and then move the mouse up or down to correspond to the new Output value desired. The new value is then written to the Output parameter of the loop. The arrowhead remains in the new position. Output Limits These cyan arrowheads are vertically positioned relative to the OUT_READBACK bar graph to indicate the high and low Output limits. Although these arrows cannot be dragged with the mouse, the values they indicate can be modified by using the block's detail display. Tick marks This vertical arrangement of black lines is used to indicate percentages of PV and Output scale. PV bar graph This graph indicates the value of the PV parameter for the block, which is the same as the value displayed in the PV display box. Setpoint Slider/Working Setpoint To move the Setpoint Slider, hold down the left mouse button with the cursor over the arrowhead and then move the mouse up or down to correspond to the new SP (setpoint) value desired. The new value is then written to the SP parameter of the loop. The arrowhead is controllable only when the actual mode is AUTO, MAN, or OOS. Another arrowhead (not displayed in the above figure) with the same size and movement range as the Setpoint Slider but with a transparent fill color and a black border indicates the Working Setpoint (SP_WRK) of the block. This arrow's movement range is restricted within the Setpoint Limit arrows and is the actual SP used by the controller to calculate output moves. When SP and SP_WRK have the same value, SP_WRK is superimposed upon SP and, therefore, is not distinguishable from SP. The Working Setpoint is visible as a separate entity when setpoint ramping prevents SP_WRK from going to SP immediately. Setpoint Entry Setpoint Entry is the 3-D recessed box displaying the SP value of the block. The Setpoint Entry box is next to the Setpoint Slider. The background color of this box changes from black to orange or red when the PV status becomes uncertain or bad, respectively. Clicking this box produces a dialog box that prompts you for an SP (setpoint) value. A setpoint change is accepted while the actual mode is AUTO, MAN, or OOS. The valid range for input is defined by the engineering unit EU0 and EU100 values of PV_SCALE. Valid input ranges from 0 to 100 percent of PV_SCALE. The SP value is then visible in the decimal format provided by PV_SCALE.F_DECPT when this value has 0, 1, 2, or 3 digits. Setpoint Limits These white arrowheads are vertically positioned relative to the PV bar graph to indicate the high and low SP limits. Although these arrows cannot be dragged with the mouse, the values they indicate can be modified using the block's detail display. Deviation Alarm Limits These blue arrowheads are vertically positioned relative to the Setpoint Slider to indicate the high and low SP-PV deviation alarm limits. Although these arrows cannot be dragged with the mouse, the values they indicate can be modified using the module's detail display. PV Alarm Limits These blue arrowheads are vertically positioned relative to the PV bar graph to indicate the high high, high, low, and low low alarm limits for the PV. Although these arrows cannot be dragged with the mouse, the values they indicate can be modified using the block's detail display. Output EU 0 This area shows the value corresponding to 0% of scale for the Output. PV EU 0 This area shows the value corresponding to 0% of scale for the PV. Detail Display button This button is used to open the detail display for the PID block. Trend button This button is used to open the trend display for the PID block. A trend display is a popup picture that shows a one second trend trace for each of the module's main operating parameters. The trend traces start when the picture is opened and stops when it is closed. Module Faceplate button This button is used to open the module faceplate display.

29 This picture shows the total number of active alarms, the number of unacknowledged and suppressed alarms for the current area, and lists active alarms by: Ack - the acknowledge status. Time In - the time at which the alarm went active. If the alarm is active when a controller switchover occurs, the alarm is regenerated with a new time stamp. Unit - the name of the unit that owns the module that is in alarm. Module/Parameter - the name of the module that contains the alarm and the active alarms. Description - a description of the module. The user creates the module description in the DeltaV Explorer or Control Studio when the module is created. Alarm - a word such as COS (Change of State) or CFN (Change from Normal) that appears when the alarm is active. The alarm word is a characteristic of the alarm type. Message - a message associated with the alarm. The format of the alarm message is determined by the alarm type. The values in the alarm message are represented by userdefined parameters. Priority - a word such as Critical, Warning, Advisory, or any user-configured priority that indicates the importance of an event to the operator and the priority of the alarm at the workstation. The priority affects the order in which the alarm appears in this picture and in the Alarm Banner. ALARM BANNER The Alarm Banner is in the lower section of the screen in the operator's interface. It provides buttons for the five most important alarms monitored by this workstation for the current DeltaV user. Dualmonitor workstations display the ten most important alarms. The Alarm Banner enables the operator to focus on the most important alarm first. Any alarm of a priority (typically lower priority alarms) not shown in the alarm banner do not sound the horn on that workstation. The buttons show the name of the modules, units, and devices in alarm. The banner can show all active process alarms in a module, or you can configure the alarm priorities so that only the most important alarms for a module or unit occupies a position in the alarm banner (see the alarm field description). The operator can access the display needed to correct the alarm condition by clicking the álarm in the Alarm Banner. For device alarm, the alarm banner shows alarm with the Warning priority. Each device alarm may be triggered by one of several device conditions. The banner shows one active alarm even if more than one device condition is causing the alarm. For example, if two device conditions are causing a Maintenance Alarm, the banner only shows one Maintenance device álarm. There is also an extended information button next to each alarm button (refer to the following figure). When you click an extended information button, the associated alarm's time stamp, parameter name, alarm word, and alarm priority are displayed at the bottom of the banner. If you enable the Primary Control button and click one of the five alarm buttons (for example, CAS5), the operator's interface displays the primary control display (in the main process graphic area). If you enable the Faceplate button and click one of the five alarm buttons, the operator's interface displays the faceplate assigned to the module. Power Boiler Training Simulator 29 of 33

30 SUPPRESSED ALARMS The Alarm Suppress picture displays up to 250 suppressed alarms in areas within the current user's span of control. Use this picture to view suppressed alarms and to unsuppress alarms. Open the Alarm Suppress picture either of the following ways: from the DeltaV Operate toolbar, click or click and then select AlmSupp. from the Alarm Filter picture, click from the top of the picture when suppressed alarms exist. Suppressed alarms are listed by Module, Parameter, Description, Area, Unit and Time In. This picture shows the total number of alarms and the number of unacknowledged and suppressed alarms for the current area. To unsuppress an alarm, select the alarm and click the unsuppress button from the details toolbar. Note You cannot use this picture to suppress an alarm. Use the Detail picture for the module that is in alarm to suppress the alarm. For more information on suppressing alarms, refer to the Suppressing Alarms topic. From the Alarm Suppress picture, click to open the Area Select picture. Use the Area Select picture to select the area(s) from which you want to see suppressed alarms. The details section of this picture uses the Alarm Summary Object. For more information on the functions available through the Alarm Summary Object, refer to The Alarm Summary Object topic and the DeltaV Operate online help. Power Boiler Training Simulator 30 of 33

31 AREA FILTERING The Area Alarm Filtering (AlarmFilter) picture enables you to turn on the areas from which you want to see alarms and to turn off the areas from which you do not want to see alarms. An area that has been turned off is filtered. Use the Alarm Filtering picture to filter alarms in up to 100 areas in your DeltaV system by the following steps: Check the box next to an area to display that area's alarms in the Alarm Banner, the Alarm List picture, the Alarm Suppress picture. Clear the check box to filter alarms by preventing that area's alarms from displaying in the Alarm Banner, the Alarm List, the Alarm Suppress, and the Alarm Filter pictures. Click the All On button to see alarms from all areas that can be turned on. Click the All Off button to filterr (that is, to prevent from displaying) alarms from all areas. Click an alarm area to see detailed information (for example, time of alarm, module, description, parameter, alarm description, and message) on the alarms for that area. Click the Description column in the detailed information area to open the Faceplate picture, the Primary Control picture, or both pictures for that module. This is known as Alarm Direct Access. Two buttons in the Alarm Banner enable and disable Alarm Direct Access. The total count of unacknowledged alarms, active alarms, and suppressed alarms for an area that is checked is displayed next to the plant area name. The total number of alarms, the number of unacknowledged alarms, and the number of suppressed alarms are shown across the top of the area alarm details section. The details section of this picture uses the DeltaV Alarm Summary Object. For more information on the functions available through the Alarm Summary Object, refer to The Alarm Summary Object topic and the DeltaV Operate online help. Whenever an area is being filtered or an alarm is being suppressed, an indicator appears on the Alarm Acknowledge button on the Alarm Banner, as shown in the following table.

32 Alarm Filtering only affects what is seen through DeltaV Operate. It does not affect the event chronicle database or the association between workstations, users, and alarms that is defined in the DeltaV Explorer or the area keys assigned in User Manager. Alarm Filtering affects only the machine on which the Filter settings were made and is independent of the user. If you filter alarms and then log off the machine, the next user to log on will not see alarms from the area that you filtered. ACKNOWLEDGING ALARMS If there are any alarms associated with a control module and an alarm occurs during operation of the process, the module name will be displayed in the Alarm Banner at the bottom of the operator's screen. Alarms have a descending priority of Critical, Warning, or Advisory and a status of acknowledged or unacknowledged. Unacknowledged alarms are more important than acknowledged alarms. For alarms with equal priority and status, alarms with a more recent time stamp are more important than older alarms. If there are more than five alarms, the five most important alarms are displayed. Selecting the small button to the right of an alarm button displays additional information about the alarm in the line below the alarm buttons. The operator can click an alarm button to go immediately to the screen identified as the Primary Control picture for that module. To acknowledge alarms, you can Click the large Alarm button in the lower right corner of the Alarm Banner to acknowledge alarms in the main picture. Click the Alarm button at the bottom of the module's Faceplate picture to acknowledge all alarms in that module. If there's an audible alarm, click the Silence Horn button to silence the alarm. This does not, however, acknowledge the alarm. In addition to the alarms displayed on the process graphics, a standard alarm picture shows all active alarms and their priorities. To see the Alarm List, the operator can click the Toolbar or select the alarmlist picture from the Open Replace dialog. Abutton on the Power Boiler Training Simulator 32 of 33
